2 Claims. (01. 280-'7.18)

This invention relates to skates which may be used on snow or ice and in one form may also be fitted with wheels to be used on any hard surface.

An object of the present invention is to provide a skate to be used on snow or ice, on which the runners are spaced to provide maximum stability.

Another object of the present invention is to provide a skate to be used on snow having a large runner area to support the wearer, and having parallel ribs to guide the skate.

Another object of the present invention is to provide a skate which may be used on snow or ice and which may also be easily fitted with wheels.

Other objects and advantages of the present invention will be apparent from the accompanying drawings and description and the essential features thereof will be set forth in the appended claims.

In the drawings,

Fig. 1 is a side elevational view of one form of my invention;

Fig. 2 is a top plan view of the skate shown in Fig. 1;

Fig. 3 is a sectional elevation on the line 3'-3, of Fig. 1;

Fig. 4 is a side elevational View of a modified form of my improved skate, showing the skate fitted with wheels; while Fig. 5 is a sectional elevation on the line 5-5 of Fig. 4.

In the form of my invention shown in Figs. 1 to 3 I provide my improved skate with a base lb] of substantial width. For instance, a skate nine inches inches long would be about 1 /2 inches wide.

The base I0 comprises two runners I I depending from the side edges of the base I0 and extending longitudinally of the base, and a fiat web portion I2 connecting the two runners II. The runners extending about 4; inch below the fiat web portion I2 and being about 95 inch wide.

I provide a toe plate I3 secured to the base It! by a rib I4 and a curved upward extension Illa of the base III.

For securing the forward portion of the skate to the shoe (not shown) of the wearer I provide the strap l5 which passes beneath the toe plate I3 and over the shoe (not shown). The strap is held against fore-and-after movement by the notches I3a in the plate l3.

The heel plate I6 is made adjustable by means of the bolt l1 extending through a slot I8 in the supporting plate I9. To securely clamp the heel plate IE to the supporting plate IS, the bolt ll is provided with a wing nut 20. The supporting plate I9 is mounted on the base Ill by the ribs 2|.

In the upright portion Isa of the heel plate I6 are two slots lBb through which a strap 22 is threaded for securement to the heel of the wearer.

In the modification shown in Figs. 4 and 5 I provide upstanding bearing lugs 23, fore-and-aft of the skate, which extend transversely of and clear across the base Ill through the openings beneath the heel and toe plates, thus reinforcing the base at these points of heavy strain. The lugs 23 are adapted to receive an axle 24 on which are mounted wheels 25 by means of bearings 26. A nut 21 threaded on the axle 24 secures the whole assembly to the base ID of the skate.

It will be observed, in both forms described, that the heel and toe plates I3, I9, the ribs 2|, I4 and Ill'a, and the runner base ID are all integral parts of a single body member, which hence may be either a casting or a forging and thus fabricated at low cost but still with ample strength to withstand the severe punishment which such skates encounter in sidewalk and other use. In the form shown in Fig. 4, the base of the body member is further reinforced by the transversely extending bearing lugs or bosses 23, which also are integral with the base.

I have thus provided a skate having a large base area that can be used on snow, as for example, for sliding down a hill and which when used on ice or snow has great stability, and may also be easily fitted with wheels in warmer weather.

Other advantages of the invention will be apparent to those skilled in the art.

What I claim is:

1. A combination ice and roller skate, comprising a one piece body member which includes a wide elongated base provided along its side edges with depending runners, two pairs of longitudinally spaced supporting ribs integral with said base and extending upwardly along its center line, horizontally extending heel and toe supporting plates, each integral with one pair of said ribs, two bearing bosses integral with and reinforcing the base, each extending transversely thereof within and through the space between the ribs of each of said pairs, an axle mounted in edges with parallel depending runners, rib means integral with said base and extending upwardly along its center line, horizontally extending heel and toe supporting platesintegral with said rib means at the top thereof, two bearing bosses integral with and reinforcing said base, each of said bosses extending upwardly from said base and transversely thereof between its side edges, an axle mounted in each bearing boss, wheels carried by said axles and extending below said runners, and means mounted upon said plates for securing the skate to the foot of the wearer.
